of the chamber to fire longitudinally thereof.

The gas issuing from the bottom row of burner nozzles will therefore flow next to the work and serve as a protective blanket tending to prevent the work from being oxidized or sealed by air tending to enter through the work slot 30, and also by the air flowing above the bottom row.

The pressures of the air and gas supplied to the burners will ordinarily be equal and relatively low in order that the gas flowing through the nozzle passages 15 and the air flowing through the passages 19 may be discharged in streamline flow without substantial turbulence. As a consequence of such flow the air and gas will mix primarily by interdiffusion with the consequent production of a relatively long flame which is highly luminous or radiant. The heat from the flame thus produced penetrates the gas blanket and hence the work is heated primarily by radiation from the flames of combustion.

What I claim is:

1. A tile for a gas burner comprising a block which intermediate its ends and for a substantial portion of its length is cruciform in cross section and which is axially apertured to form a nozzle.

2. A tile for a gas burner comprising a block which intermediate its ends and for a substantial portion of its length is cruciform in cross section and which at one end is formed as a tube,

'the tube passage being extended to the otherend of the block.

3. In a gas burner, the combination of a casing through which air may flow, a plurality of bodies extending across and supported by said casing in spaced relation, each of said bodies comprising a multi-nozzled refractory structure and a conduit for supplying gas to said nozzles, the said structure between said nozzles being wedge-shape in cross section.

4. In a gas burner, the combination of a casing through which air may flow, a plurality of bodies extending across and supported by said casing in spaced relation, each of said bodies comprising a multi-nozzled refractory structure and a conduit for supplying gas to said nozzles. the said structure comprising a plurality of individually nozzled blocks arranged side by side in a row, each block being cruciform in cross section on a plane at right angles to the axis of its nozzle. a

5. In a gas burner, the combination of a casing constituting a conduit for air, a plurality of elongate and hollow bodies extending in spaced parallel relation across the conduit 'and constituting conduits for gas, a series of nozzle blocks for each of the gas conduits,'the blocks being arranged side by side in abutting relation with their backs abutting against their respective conduits and converging wedge-fashion forwardly therefrom, the nozzles constituting extensions beyond the apex of the wedge, and being in direct communication with their respective gas conduits.

6. In a gas burner, the combination of a casing constituting a conduit for air, aplurality of elongate and hollow bodies extending in spaced parallel relation across the conduit and constituting conduits for gas, for each of the gas conduits, the blocks being arranged side by side in abutting relation with their backs abutting against their respective conduits and converging wedge-fashion forwardly therefrom, the nozzles constituting extensions beyond the apex of the wedge, and being in direct communication with their respective gas conduits, and means for anchoring the blocks to their conduits comprising a section of tubing embedded in each block and extending therefrom into the conduit as an anchoring post.
